Answer:

117°

Step-by-step explanation:

The angle is obtuse, so thus greater than 90°. And the angles of a triangle must always add up to 180°, so 31 + 32 = 63, then 180 - 63 = 117°

The function on the table is decreasing on the interval [-2, 0).

<h3>Over what interval is the function shown in the table decreasing?</h3>

A function is decreasing if, as x increases, f(x) decreases.

We can see that at x = -2, f(-2) = 12.

Then at x = 0, f(0) = 0.

And for the value after that:

x = 1, f(1) = 3

So now the function increases. Then we conclude that the function is decreasing on the interval [-2, 0), and after that the function increases.

One week Jenna rented 4 DVDs and 2 Video Games for $18, the next week she rented 2 DVDs and 1 video game for 9$. Find the rental
tangare [24]
To do this problem you have to create two equations. one would be 18=4x+3y
an the other would be 9=2x+y. in this eqaution X is the number of DVDs and Y is the number of Video games. Then you solve for Y in the second equation and you get y=-2x+9. After that you then input this equation in for the other equation and you will have 18=4x+3(-2x+9). you solve for X in this problem and then you take the answer of x and put it in for x in the other equation. 
so, 18=4x-6x+27
subtract 27 and add the 4x and -6x
-9=-2x
x=4.5
after this you put it in the other equation
9=-2(4.5)+y
multiply the -2 and 4.5
9=-9+y
add the 9
y=0
